Constricted tubes appear in many engineering as well as biological systems such as blood vessels or pulmonary airways. The aim of this article is to test the ability of different turbulence models to predict the flow field ...

Electronic cigarettes (e-cigarettes) have become very popular recently because they are marketed as a healthier alternative to tobacco smoking and as a useful tool to smoking cessation. E-cigarettes use a heating element ...

Dynamic torsional vibration dampers are for a long time inherent integral components of internal combustion engines. One of the most common types of the dynamic dampers is a silicone damper. It has been, for many years, ...

The presence of aerosol deposition hot-spots in human airways presumably contributes to development of various diseases. The overall aerosol deposition in human lungs can be predicted with sufficient accuracy nowadays. ...

Medical aerosols are key elements of current chronic obstructive pulmonary disease (COPD)
therapy. Therapeutic effects are conditioned by the delivery of the right amount of medication to
the right place within the airways, ...

The present paper provides an experimental study and optimization of multi-hole effervescent atomizers for industrial burners using oil-based fossil, bio- or waste fuels with prospects of emission reduction. Several ...

Article deals with numerical simulations and its verification by experiments in trachea of idealized geometry of tracheobronchial airways by using unsteady RANS approach. Respiratory cycle was simulated by sinusoidal ...
